How to Prepare Rocks and Stones for Painting

Cleaning is the first thing I do to prepare my rocks for painting. 

  • Use a little dish detergent and water
  • Scrub the rocks to remove dirt
  • Rinse well
  • Allow the stones and rocks to dry completely
  • CLEANING TIPS: 
    • I like to do several stones at one time in a bucket
    • Dirt from the stones may clog the pipes, so be sure to dispose of the cleaning water in a suitable place
    • To sanitize the stones after washing and rinsing, I add a little bleach to a bucket of clean water, then rinse well 

Many rocks need just a good cleaning and no other preparation for painting.
 
Priming will make your project go much easier for certain types of rock and stones. 

Candidates for priming: 
  • Smooth stones
  • Dark-colored rocks and stones
  • Rough, porous, and/or pitted rocks or bricks

SMOOTH STONES 

I purchased these landscaping stones in the garden department of a big box store. 
 

They are a great shape for rock painting, but the smooth surface makes it difficult for paint to adhere properly. Without priming the rocks first, my design and hard work can peel right off. 

To prime these stones (after they've been cleaned and dried), I just apply 1 or 2 coats of white (or light colored) acrylic or craft paint. 


The light primer not only helps subsequent paint layers adhere but also brightens subsequent colors.


Update August 2017: My preferred primer is gesso. Learn more about gesso and how it is used.


DARK-COLORED STONES 

A coat or two of white or light-colored paint applied to dark stones helps brighten subsequent paint colors as illustrated below.

PITTED OR ROUGH STONES OR BRICKS

There are several ways to prime pitted or rough stones.

Acrylic paint can be used to fill the pits (if they aren't numerous or deep) by dabbing the paint into any little crevasses or holes. 


Landscaping bricks, edgers and pavers are very rough. I like to brush on a product called KILZ to prime them before painting.
 


Sometimes, I smooth wood filler over a rock's holes and cracks to fill them before applying a primer and/or painting. 


Update August 2017: For slightly pitted stones, I now use super heavy gesso. Learn more about gesso and how it is used.




To protect and seal my rocks once they are painted, I brush on Americana DuraClear Satin Varnish. 
 

These are the supplies and methods I prefer for painted rocks preparation and protection.

  2. Does spray paint work very well to mass prime/paint a bunch of stones?

    1. That's a good question. I've never used spray paint but it would sure be a time saver. You may want to try it on a few stones first to make sure 1) it adheres to the stone and 2) that subsequent acrylic paint adheres to the "primed" stone. (You wouldn't want to use spray paint with a glossy or enamel finish.) I would try this item from Krylon. http://www.krylon.com/products/colormaster-primer/
      Let me know if it works.

    5. Thank you so much for the compliment, Joette.
      It can be difficult to find good painting rocks in certain areas. If you find it necessary to purchase them, stay away from the polished stones, e.g., those at Michael's (the paint won't adhere well.)
      I have purchased stones from Home Depot and been very happy with them. (Here's a link to my blog post about them: http://paintingrocks.blogspot.com/2014/06/where-can-i-find-rocks-for-painting.html
      Amazon.com sells stones (search for beach pebbles).
      If you're in the U.S., the post office has a flat rate shipping service and you could enlist a friend to ship you some rocks from their area.

    6. I'm trying to paint a rock. I'm just starting the colors. Normally I write on them, then seal them with an acrylic coating. The paint doesn't cover! Do I need to use a primer first?

      Delete
    7. It sounds like you do need a primer, Holly. You can use white acrylic paint as your primer. It will give the colors something to adhere to and also make the colors brighter. Here are some primer guideline, if your rock is a darker color a primer definitely helps. If you're painting a light-colored rock, a primer is not as important. If your rock is super smooth, a primer will help paint adhere better to the rock.

  6. Hello, I was looking to ask what kind of paint do you find that works the best. There are just so many brands, is acrylic better ?

    ReplyDelete
    Replies
    1. Bella, the quick answer is yes, acrylic is better. It dries fast and is easy to clean up.
      I use both acrylic and craft paint acrylic in the 2 oz. bottles. I have no preference for a brand and choose the paint based on the color I like or want. (Note: The craft paint acrylic is a little thinner than the acrylic and more coats may be needed.) For painted rocks displayed outdoors, I use Anita's Yard & Garden Outdoor Paint. Deco Art also makes a version called "patio paint."

  7. What is the best way to preserve your painted rock that is going to be exposed to the weather (all seasons, including winter)

    ReplyDelete
    Replies
    1. Terry, for my outdoor rocks I use several coats of Mod Podge Outdoor, followed by several coats of Delta Ceramcoat Exterior/Interior Varnish. The Mod Podge gets "tacky" in humidity and is the reason I apply the Delta Ceramcoat over it. I've heard some people use sealers meant for boats but I've never tried them. I have some rocks that have been outdoors for years in all seasons and the painted rock has been fine and some others have had the paint flake off. I'd suggest checking an outdoor painted rock every year and apply another coat of sealer if you think it needs it. You can read more about my experience with sealers on this blog post: http://paintingrocks.blogspot.com/2012/07/how-to-seal-and-protect-painted-rocks.html

    2. Do the white pebbles have a wax type finish on them? If so, how to you prepare them for painting. I know the polished rocks scratch. I would think even with primer the paint still would not adhere well?

    1. Boni - Thanks for letting me know you appreciate all the info I share.
      If you're just starting to paint rocks, I'd suggest an inexpensive white acrylic paint (or crafter's acrylic which is slightly thinned with water.) You would use this white to prime your rocks so the colorful acrylics look brighter and adhere better.
      I use various brands of acrylic/crafter's acrylic and don't have a favorite. Some of the brands I've used are: DecoArt, Apple Barrel, Folk Art, Americana, and Anita's. I buy my paint based on the color I'm looking for rather than a specific brand.
      In a nutshell, I'd say start with inexpensive acrylics and see how they work for you.

    I would like to paint on rocks in their natural state. If I prime them first, I would have to paint the whole rock,loosing its natural beauty. I tried once and gave up because I had to keep starting over. I could not get the edges/lines and details straight. I was using the smallest brush I could find. My friend said to try a short stiff brush. Well, I'm going to try painting again. Any advice?

    1. Thank you for the compliment, Hope.
      You can definitely paint rocks in their natural state without priming them. Just make sure the rock isn't too smooth or slick otherwise the paint won't adhere properly. Painting details takes practice and the right brush is very important. You would think a small, short brush would work but I've found a script liner (long and thin) gives the best results for detail painting. Nail art brushes are another good alternative.
      Here are 2 blog posts I wrote about brushes which you may find helpful: http://paintingrocks.blogspot.com/2014/06/3-of-my-favorite-rock-painting-brushes.html AND http://paintingrocks.blogspot.com/2015/09/nail-art-brushes-great-set-of-tools-for.html

  21. Hi Cindy, I'm doing a project with upper elementary students and they would like to write inspirational words/phrases on one side and their names on the other (gift for their teacher). I know you primarily use acrylic paint. Would it be possible to use sharpies or some other more pointed instrument so the finished product is a readable as they want it to be?

    ReplyDelete
    Replies
    1. Greetings. Your project sounds like a wonderful idea for the teacher. It IS possible to use Sharpies and other art pens on rocks. The problem occurs when you apply a sealer to protect the art. Many of the sealers may cause the pens to bleed and ruin the words/design. Thin coats of a spray-on sealer generally work best but I recently had a problem with the can dripping and blurring my design. Another alternative sealer (especially if the stones are on the small side) is clear top coat for fingernails. I've tested this and the design shouldn't blur but I'm not sure how durable this alternate sealer will be and you may want to test it first with the type of pen your students are using.

  27. Hi Cindy! I am new to rock painting, and I have been scouring your blog for tips. Very helpful! I have a question regarding pens. I bought Sharpie Paint pens, but I'm wondering if I should go ahead and get the Posca pens. Here's what I'm running into: while I'm writing a long word, the paint starts to get too thin, and I have to stop and "pump" the marker on a piece of paper to get the paint to flow again. And then I usually get a big blob on the rock when I get back to it. :( Are the Posca markers more continuous than this? Do they keep writing like like a typical marker-on-paper, or do they require pumping to get the flow as well? It's very frustrating - and then when I try to go back over the word where the paint got too thin, the newly primed marker grabs some of the paint and I get a bald spot on the rock. Boo!! Do you have any suggestions? What am I doing wrong? Do the Posca markers do this? Thank you for pointing me in the right direction! ~ Anna in TX

    1. Hello. I'm happy to hear you find my tips helpful but sorry you're having difficulty with paint pens. I use the paint pens for detail work and have never tried to write a long word. The Posca pens do have a "bead" inside and must be shaken so I'm worried you would have the same problem with them. (By the way, you're not doing anything wrong. It's the nature of the beast.) Since Posca pens can be pricey, my suggestion would be to purchase just 1 Posca pen and see how it works for you. Another suggestion would be to make sure your rocks are very smooth. Some rock artists use dip pens and ink but I haven't used these myself. I wish I could be more helpful.

  35. Hi, Cindy T,
    As a lifetime artist, I've been painting rocks (and eggshells!) for many years and use them painted AND natural in my art on canvas, mat board, wood, etc. I see in most of your questions the problem with sealing the art on rocks and the sealer causing the artwork to smear or run. I learned LONG ago to brush a thin layer of Mod Podge onto the artwork FIRST, let it dry COMPLETELY, sometimes only about 20 minutes, depending upon how thick you've applied the Mod Podge, and THEN using spray or brush on acrylic to save the artwork. It too me many mistakes to learn this simple "trick", but once learned, it works on nearly ANY surface or acrylic painted surface. .. and helps keep you from crying over losing such lovingly and painstakingly time and love you've put into your work. Thanks for helping out so many new artists to this fun and therapeutic works of stone art.

    1. Hi Katie.
      Thanks for commenting about the use of Mod Podge prior to using a sealer. At one time I only used Mod Podge and then discovered that it became "tacky" in humid weather. Since then, I've continued to use Mod Podge before adding a brush-on sealer. I haven't experienced any smearing either when using the Mod Podge to "set" the paint. It's good to get confirmation by another artist that this technique does work.

  36. Hi Cindy, the information here is very helpful for beginners! I have a access to a ton of round flat smooth rocks that I gathered for a school project. They have about 2 to 3 inch surface to paint Since we have 100+ rocks to prime, what is the most efficient and cost effective way to prime the rocks? We want to leave the rock color in its natural state, but worried that the smooth surface will not be a good base for the paint. I was thinking mod podge as a primer and then using the recommended low odor spray for the sealer. What do you recommend? I would like to use glow in the dark paint. Have you ever used? Have you used a Nail Stamper for designs before? I thought this may be fun, but not sure if it will work. Also, looking for ideas to display the rocks. Each class (25 students) will decorate their own rock and have their own display. We are thinking of a wall plaque possibly, a decorative tray, but looking for more ideas, something outside maybe. Any ideas you have to display 25 rocks together as one art piece would be great. Thank you!

    1. Hello. I'm happy to hear you find the information on my blog helpful. The rocks you've collected sound perfect for rock painting! I have painted on smooth rocks without priming them and the paint has adhered well. (The problem is when the rock is coated with a waxy substance.) However, Mod Podge should be fine as a primer. That said, I would recommend doing a few "practice" rocks before doing the class project. Prime them, paint them, seal them and see how it goes.
      I have used glow-in-the-dark paint and it worked well. Here's a blog post I wrote about it: http://paintingrocks.blogspot.com/2013/02/painted-rocks-how-to-get-yours-noticed.html
      I have not used a nail stamper but if the rock is smooth enough, I don't know why it wouldn't work.
      Your ideas for displaying all 25 rocks together sound great. For outside display, I've heard of classes creating rock gardens. Note: even if a rock has been sealed, it will eventually fade when left outdoors.
      I wrote a blog post about display stands for rocks but it's for individual rocks: http://paintingrocks.blogspot.com/2015/02/how-to-display-painted-rocks-store.html
      Good luck with your rock painting project. I'm sure it will be a great success!
